The Winco DR100F4 is a 100 kW standby diesel generator powered by an FPT Industrial N67-family 6.7-liter six-cylinder turbocharged diesel engine with a Stamford alternator. A three-phase-only unit (277/480V), it is one of the larger models in Winco's enclosed DR diesel standby series. EPA Tier 4 Final certified. 100% US-made in Le Center, Minnesota since 1927.
At 100 kW, the DR100F4 is serious commercial infrastructure — serving buildings with significant electrical loads, life-safety systems, and code-mandated backup power requirements. The DR series enclosure provides outdoor-ready installation with sub-base fuel tank and automatic start capability.
Winco has manufactured generators in Le Center, Minnesota since 1927 — a continuous US manufacturing record unmatched in the industry. At 100 kW, the DR100F4 uses an FPT Industrial N67 six-cylinder engine and a Stamford alternator, both globally non-proprietary and independently supported.
For federal contractors, municipal utilities, healthcare systems, and educational institutions with Buy American Act or procurement mandate requirements, the DR100F4 qualifies as a US-manufactured product at a competitive price point. The FPT N67 engine is serviced through CNH Industrial's global dealer network (Case IH, New Holland, Iveco) — a distribution network that reaches even rural areas where Winco's own dealer presence is minimal.
Oil and fuel filter changes every 500 hours or annually — the annual interval is critical for standby units where diesel sits in tanks and degrades. The FPT N67 six-cylinder engine has a larger oil sump and filter capacity than smaller four-cylinder platforms; consumable costs are proportionally higher. Engine consumables are available through CNH Industrial dealers and standard diesel parts suppliers.
Stamford alternator maintenance covers brush wear, bearing condition, and winding insulation — routine tasks for any qualified generator technician. Transfer switch contacts should be exercised weekly. Major overhaul at 20,000 hours.
PowerGen services Winco DR units throughout the Bay Area and Northern California. The FPT Industrial N67 and Stamford components mean we source parts through standard diesel channels — the same supply network we use for Cummins and Caterpillar. For clients with Buy American requirements or strong preferences for US-made standby infrastructure, the DR100F4 delivers 100 kW of reliable diesel standby from a proven American manufacturer.

Frequently Asked Questions
What is the standby kW rating of the DR100F4?
The DR100F4 is rated at 100 kW standby. It is a three-phase-only unit (277/480V).
What engine does the DR100F4 use?
The DR100F4 uses an FPT Industrial N67-family 6.7-liter six-cylinder turbocharged diesel engine from CNH Industrial. The N67 is a widely deployed industrial platform used across Case IH, New Holland, and other CNH equipment lines worldwide.
What makes Winco different from Generac or Kohler?
Winco uses non-proprietary FPT Industrial engines and Stamford alternators — both globally supported components that any qualified diesel technician can service. Winco has manufactured 100% in Le Center, Minnesota since 1927. Generac and Kohler use proprietary engines and offer connected monitoring platforms and denser dealer networks, but require proprietary parts and service.
Is the DR100F4 EPA Tier 4 Final compliant?
Yes. The DR100F4 is EPA Tier 4 Final certified — meeting current non-road diesel emissions standards required for new installations.
Where are Winco generators made?
100% in Le Center, Minnesota. Winco has operated at that US facility continuously since 1927, making it America's oldest generator manufacturer.
What are the service intervals for the DR100F4?
Oil and fuel filter changes every 500 hours or annually. Air filter inspection at 500 hours. Major overhaul at 20,000 hours. Transfer switch contacts should be exercised weekly during standby to prevent oxidation.
Who services Winco generators in Northern California?
PowerGen services Winco DR units throughout the Bay Area and Northern California. The FPT Industrial N67 engine and Stamford alternator are non-proprietary — parts come through standard diesel supply chains, giving us full service capability without a dedicated Winco dealer.
